SimonxNia is my OTP.
Simon is the perfect guy. He's good looking, he's not loud and annoying like most guys, and he actually prefers being quiet. He only cares about other people, to the point he gives everything anyone can give for others, not to mention he's romantic. He was the first guy that I ever thought "I'd love to be in a romantic serious relationship with him." about.
And Nia. She's so similar to Nono there's no way I could not love her. Though I love her for her own character too, not just because she's similar to Nono.
